searchviewを使用してrecyclerviewを検索する

Question

解決済み、私はモデルを静的に使用する必要があります。ありがとうすべて

私はこのトピックfilter recycler view using search viewを通過しました。私はすべてのステップを実行しました。今私はリサイクラビューで検索するとき、それは私のリサイクラビューをフィルタリングしますが、私はスペースを押して、削除されたアイテムを表示しない文字を削除します！私のリサイクル業者のビューは検索後も空です。

これは私のRecyclerViewアダプタです：

     this.context = context; 
     this.myModels = myModels; 
    } 

    @Override 
    public myRecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View v = LayoutInflater.from(context).inflate(R.layout.channels_layout, parent, false); 
     return new myRecyclerViewHolder(v); 
    } 

    @Override 
    public void onBindViewHolder(myRecyclerViewHolder holder, int position) { 

     final NewsModel newsModel = myModels.get(position); 
     holder.edt_Title.setText(newsModel.title); 
     holder.edt_Dis.setText(newsModel.discription); 
     holder.txt_Category.setText(newsModel.category); 
     Picasso.with(context).load(newsModel.image).into(holder.img_Channel); 
     holder.btn_Join.setOnClickListener(new View.OnClickListener() { 
      @Override

これは私のnewsModelsです：

import java.io.Serializable; 

/**

*/ 

public class NewsModel implements Serializable { 


    public String id; 
    public String title; 

    public String discription; 
    public String image; 
    public String category; 
    public String username; 
    public NewsModel(String title, String description,String image,String id,String category,String username) { 
     this.id = id; 
     this.title = title; 
     this.discription = description; 
     this.image = image; 
     this.category = category; 
     this.username=username; 
    } 

    public NewsModel() { 
    } 
} 

、私を助けて感謝してください。私の悪い英語を申し訳ありません！

Answer 1

私はまた、チュートリアルを使用していますし、それが成し遂げます。私は自分のアクティビティを実装しています

implements SearchView.OnQueryTextListener 

また、私はこの方法でsearchviewを使用しています。

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.close_menu, menu); 

    final MenuItem item = menu.findItem(R.id.action_search); 
    final SearchView searchView = (SearchView) MenuItemCompat.getActionView(item); 
    searchView.setOnQueryTextListener(this); 
    return super.onCreateOptionsMenu(menu); 
} 

と残りのメソッドを安静にしてください。
